I find Boeing's dismissal of this as not being a safety concern unconvincing. Boeing spent the money adding this to their design. They spent the money adding the capability to every plane they had. And they thought it was important enough that they shouldn't be charging airlines for it, unlike the addition of a backup sensor (which wasn't considered important enough to be delivered standard). What was the thinking when doing the review? Hey, here's this feature we thought was important enough that we added several costs without charging airlines for it, while we were nickel and diming them on backup sensors, but actually it was all a big mistake. We were just being generous on this for no reason at all?
